Washi (和紙) is a uniquely beautiful type of paper from Japan. This tea can is wrapped in a specific kind of washi paper called Chiyogami (千代紙), and holds approximately 40 grams of matcha powder. The plastic inner cover keeps the can airtight, but the can is made primarily for frequent use of the matcha powder contained.
STORAGE TIPS: For long term storage (1 month or longer without opening), be sure to double ziplock your bag or can, and store in the refrigerator. Be sure to allow the temperature in the container to equalize with room temperature before opening to prevent condensation...this takes about 3-4 hours.
